REiToRT DEOxlDIZING-FURNACE.

SPECIFICATION fanning part of Letters Patent No. 291,298, dated January 1, 1884.

' Application filed July 5, 1883. (X0 model.) i

To CLZZ whom it nut/y concern.) I

Be it known that I, ISRAEL D. CONDIT, Jr., of Millburn, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Retort Deoxidiziug- Furnaces, of which the following is a full,

taken through the line 3 y, Fig. 1. Fig. 3 is a sectional elevation of the lower part of one of the retorts.

The object of this invention is to obtain as 5 large a heating-surface and body of ore to be acted upon as can be worked, and also to secure great economy in the construction of the furnaces and in the time of deoxidation.

The invention consists of an inner and outer chambered furnace having a series ofconcentrically-arranged retorts and a central retort, from which extends, through the outer cham her and inner wall, a partition, the bottom of the outer chamber having the inlet-opening arranged on one side of the said partition, while in the upper part of the inner wall is a passage arranged on the opposite side of the partition, the discharge or outlet opening being so disposed as to cause the products of combustion to travel over-the greatest area, substantially as hereinafter more fully set forth and claimed.

The furnace rests upon a pier, A, of stone or iron, of such aheight as to allow the ore to descend easily from the retorts B to the puddliug or. other furnace in connection with which the deoXidizing-furnace is used. The furnace is preferably made of circular form, and consists of an outer wall, 0, an inner wall, D, a cross-wall, E, and the retorts B. The retorts B are made oval in form, and are arranged one in the center of the furnace and the others ina circle concentric with the central retort and connected with the inner wall, D, the said retorts being placed with their longer diameters in the lineof the said wall D, as shown in Fig. 1. The crosswall E extends from the outer wall, 0, to the center the said flue F, and enter the flue G through an opening, I, in the upper part of the wall D, at the other, side of the cross-wall E from the inlet-flue H. The products of combustion circulate through the flue G, and escape from the lower part of the said flue G through the outlet-flue J, and are conducted to the boiler-furnace or to the chimney, as may be desired. By this construction is formed a continuous passage for the heated products of combustion around the retorts B from the inlet-fluc H to the outlet-flue J. The retorts B are made of fire-clay, and the bottom courses, K, of fire-brick, upon which the said retorts rest, are successively withdrawn from the discharge-pipe L, so as to form a tapering bottom, as shown in Fig. 3, and thus prevent an accumulation of ore on the said bottom. The retorts B are designed to be filled through pipes or openings in the top or cover M from a hopper, which is kept full, so as to distribute the ore to each retort as fast as it is withdrawn through the discharge-pipe L at the bot tom of the said retort. The cover M is formed of fire-clay tiles, and is of such a shape and size as the form and size of the furnace may require. The furnaces can be built of rectangular form, if desired, and in this case can be made double by placing two back to back against a division-wall.

I do not abandon or dedicate to the public any patentable feature set forth herein and not hereinafter claimed, but reserve the right to claim the same either in a reissue of i any patent that may be granted upon this application,or in any other applications for Letters Patent I may make.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The deoxidizing furnace having the inner and outer chambers, F G, the central retort, B, the inner wall, D, having the series of con IOG centricallyarranged retorts B, and the parside of the partition E, While the inner wall,
